It's springtime and birders, rock climbers, wildflower lovers and maybe even some long-lost U2 fans are flocking to the boulder-strewn desert wilderness just east of Palm Springs. But unless we act quickly to curb climate disruption, soon the one thing they won't be able to find in Joshua Tree National Park is an actual Joshua tree.

From the time John Muir founded the Sierra Club in 1892, we have known how to stand up to the forces that would destroy the treasured landscapes that are so essential to human happiness. Our historic adversaries -- mining, logging and development interests -- have always been formidable. But now climate disruption poses an even bigger threat to those places. And the dirty energy industries responsible for climate change are even more powerful and relentless in resisting our efforts.

While coal and oil are dirty vestiges of the 19th century that pollute our water and air, solar projects represent a fusion of cutting edge innovation with old-fashioned can-do spirit.

Today, being good stewards of our land, water and wildlife requires that we do everything we can to end our dependence on dirty energy, especially by moving aggressively to replace coal and oil with clean energy solutions.

We can take our first steps toward this goal by making our homes and offices as energy-efficient as possible and by putting Americans to work installing ingeniously-designed and affordable solar panels on rooftops and in urban parking lots as quickly and as aggressively as we can.

We will also have to build a number of large-scale clean energy projects, like the 700 MW Maricopa Sun project that we helped move forward in California this past week. While coal and oil are dirty vestiges of the 19th century that pollute our water and air, solar projects represent a fusion of cutting edge innovation with old-fashioned can-do spirit. But they are not without challenges.

Any large energy project carries the potential to damage wildlife habitat and natural resources -- the very treasures that our 1.4 million members and supporters work with us to safeguard. In the Mojave Desert, we worry about protecting vulnerable creatures like desert tortoises, bighorn sheep and golden eagles.

We are in a tough position. But there are solid solutions to this dilemma. We must build large-scale energy projects in the places where they will cause the least harm -- abandoned agricultural lands, defunct mines and other areas that have already been developed. By putting projects next to roads and transmission lines, we avoid the most sensitive habitat. We've worked with the Obama administration on a plan for developing these projects responsibly by setting aside special solar-energy zones that meet these criteria. When developments do cross habitat, we need to protect additional land in order to offset the damage.

Those of us who have dedicated our lives to protecting wildlife and wild places, and who are now taking on dirty coal and Big Oil, have a unique role to play in making sure that large-scale clean energy is developed both swiftly and responsibly. Because climate disruption is not only a hazard to our health and our communities -- it also poses a threat to wildlife and wildlands that outstrips anything we've seen before. If we allow it to worsen, and if we don't manage our landscapes in ways that quickly compensate for the damage already done, some of the wildlife that we treasure most here in California, like bighorn sheep, will be lost as habitat changes and they literally are left with no place to go.

That's why Sierra Club and other environmental organizations are working closely with energy developers to help them do the right thing by responsibly meeting strict environmental review, and by helping them identify the best possible locations and practices for solar and wind projects. Our volunteers and staff have already worked to improve and promote projects that add up to more than 5,000 MW of solar in southwestern states alone.

This isn't any easy endeavor, but it's one of the most important we have ever faced. We are deeply committed to creating the solar and wind energy we need, and we will be working hard to make sure it's done wisely.

The revolutionary ideals of Black Panther’s profound and complex villain have been twisted into a desire for hegemony.

The following article contains major spoilers.

Black Panther is a love letter to people of African descent all over the world. Its actors, its costume design, its music, and countless other facets of the film are drawn from all over the continent and its diaspora, in a science-fiction celebration of the imaginary country of Wakanda, a high-tech utopia that is a fictive manifestation of African potential unfettered by slavery and colonialism.

But it is first and foremost an African American love letter, and as such it is consumed with The Void, the psychic and cultural wound caused by the Trans-Atlantic slave trade, the loss of life, culture, language, and history that could never be restored. It is the attempt to penetrate The Void that brought us Alex Haley’s Roots, that draws thousands of African Americans across the ocean to visit West Africa every year, that left me crumpled on the rocks outside the Door of No Return at Gorée Island’s slave house as I stared out over a horizon that my ancestors might have traversed once and forever. Because all they have was lost to The Void, I can never know who they were, and neither can anyone else.

A week after 17 people were murdered in a mass shooting at Marjory Stoneman Douglas High School in Parkland, Florida, teenagers across South Florida, in areas near Washington, D.C., and in other parts of the United States walked out of their classrooms to stage protests against the horror of school shootings and to advocate for gun law reforms.

A week after 17 people were murdered in a mass shooting at Marjory Stoneman Douglas High School in Parkland, Florida, teenagers across South Florida, in areas near Washington, D.C., and in other parts of the United States walked out of their classrooms to stage protests against the horror of school shootings and to advocate for gun law reforms. Student survivors of the attack at Marjory Stoneman Douglas High School traveled to their state Capitol to attend a rally, meet with legislators, and urge them to do anything they can to make their lives safer. These teenagers are speaking clearly for themselves on social media, speaking loudly to the media, and they are speaking straight to those in power—challenging lawmakers to end the bloodshed with their “#NeverAgain” movement.

In Cyprus, Estonia, the United Arab Emirates, and elsewhere, passports can now be bought and sold.

“If you believe you are a citizen of the world, you are a citizen of nowhere. You don’t understand what citizenship means,” the British prime minister, Theresa May, declared in October 2016. Not long after, at his first postelection rally, Donald Trump asserted, “There is no global anthem. No global currency. No certificate of global citizenship. We pledge allegiance to one flag and that flag is the American flag.” And in Hungary, Prime Minister Viktor Orbán has increased his national-conservative party’s popularity with statements like “all the terrorists are basically migrants” and “the best migrant is the migrant who does not come.”

Citizenship and its varying legal definition has become one of the key battlegrounds of the 21st century, as nations attempt to stake out their power in a G-Zero, globalized world, one increasingly defined by transnational, borderless trade and liquid, virtual finance. In a climate of pervasive nationalism, jingoism, xenophobia, and ever-building resentment toward those who move, it’s tempting to think that doing so would become more difficult. But alongside the rise of populist, identitarian movements across the globe, identity itself is being virtualized, too. It no longer needs to be tied to place or nation to function in the global marketplace.

Deputy Attorney General Ron Rosenstein flew to Seattle for a press conference at which he announced little, but may have said a great deal.

Back in the fall of 2001, exactly one month after the 9/11 attacks, a lawyer in Seattle named Tom Wales was murdered as he worked alone at his home computer at night. Someone walked into the yard of Wales’s house in the Queen Anne Hill neighborhood of Seattle, careful to avoid sensors that would have set off flood lights in the yard, and fired several times through a basement window, hitting Wales as he sat at his desk. Wales survived long enough to make a call to 911 and died soon afterwards. He was 49, divorced, with two children in their 20s.

The crime was huge and dismaying news in Seattle, where Wales was a prominent, respected, and widely liked figure. As a young lawyer in the early 1980s he had left a potentially lucrative path with a New York law firm to come to Seattle and work as an assistant U.S. attorney, or federal prosecutor. That role, which he was still performing at the time of his death, mainly involved prosecuting fraud cases. In his off-duty hours, Wales had become a prominent gun-control advocate. From the time of his death onward, the circumstances of the killing—deliberate, planned, nothing like a robbery or a random tragedy—and the prominence of his official crime-fighting record and unofficial advocacy role led to widespread assumption that his death was a retaliatory “hit.” The Justice Department considers him the first and only U.S. prosecutor to have been killed in the line of duty.

The president’s son is selling luxury condos and making a foreign-policy speech.

Who does Donald Trump Jr. speak for?

Does the president’s son speak for the Trump Organization as he promotes luxury apartments in India? Does he speak for himself when he dines with investors in the projects? Does he speak for the Trump administration as he makes a foreign-policy speech in Mumbai on Friday?

“When these sons go around all over the world talking about, one, Trump business deals and, two, … apparently giving speeches on some United States government foreign policy, they are strongly suggesting a linkage between the two,” Richard Painter, President George W. Bush’s chief ethics lawyer who is a professor of law at the University of Minnesota, told me. “Somebody, somewhere is going to cross the line into suggesting a quid pro quo.”

On Tuesday, the district attorney in Durham, North Carolina, dismissed all remaining charges in the August case. What does that mean for the future of statues around the country?

DURHAM, N.C.—“Let me be clear, no one is getting away with what happened.”

That was Durham County Sheriff Mike Andrews’s warning on August 15, 2017. The day before, a protest had formed on the lawn outside the county offices in an old courthouse. In more or less broad daylight, some demonstrators had leaned a ladder against the plinth, reading, “In memory of the boys who wore the gray,” and looped a strap around it. Then the crowd pulled down the statue, and it crumpled cheaply on the grass. It was a brazen act, witnessed by dozens of people, some of them filming on cell phones.

Andrews was wrong. On Tuesday, a day after a judge dismissed charges against two defendants and acquitted a third, Durham County District Attorney Roger Echols announced the state was in effect surrendering, dismissing charges against six other defendants.

The path to its revival lies in self-sacrifice, and in placing collective interests ahead of the narrowly personal.

The death of liberalism constitutes the publishing world’s biggest mass funeral since the death of God half a century ago. Some authors, like conservative philosopher Patrick Deneen, of Why Liberalism Failed, have come to bury yesterday’s dogma. Others, like Edward Luce (The Retreat of Western Liberalism), Mark Lilla (The Once and Future Liberal), and Steven Levitsky and Daniel Ziblatt (How Democracies Die) come rather to praise. I’m in the latter group; the title-in-my-head of the book I’m now writing is What Was Liberalism.

But perhaps, like God, liberalism has been buried prematurely. Maybe the question that we should be asking is not what killed liberalism, but rather, what can we learn from liberalism’s long story of persistence—and how can we apply those insights in order to help liberalism write a new story for our own time.

A new study finds that many household goods degrade air quality more than once thought.

On the final day of April 2010, unbeknownst to most locals, a small fleet of specialists and equipment from the U.S. government descended on the seas and skies around Los Angeles.

A “Hurricane Hunter” Lockheed P-3 flew in from Denver. The U.S. Navy vessel Atlantis loitered off the coast of Santa Monica. Orbiting satellites took special measurements. And dozens of scientists set up temporary labs across the basin, in empty Pasadena parking lots and at the peak of Mount Wilson.

This was all part of a massive U.S. government study with an ambitious goal: Measure every type of gas or chemical that wafted by in the California air.

Jessica Gilman, a research chemist at the National Oceanic and Atmospheric Administration, was one member of the invading horde. For six weeks, she monitored one piece of equipment—a kind of “souped-up, ruggedized” instrument—as it sat outside in Pasadena, churning through day and night, measuring the amount of chemicals in the air. It was designed to detect one type of air pollutant in particular: volatile organic compounds, or VOCs. VOCs are best known for their presence in car exhaust, but they are also found in gases released by common household products, like cleaners, house paints, and nail polish.

Outside powers have been central to the nuclear crisis—but for a few peculiar weeks in February.

Of all the arguments in favor of allowing North Korea to leap into the spotlight with South Korea at the Winter Olympics—what with its deceptively smiley diplomats and even more smiley cheerleaders and the world’s most celebrated winless hockey team—one hasn’t received much attention. “It’s tragic that people of shared history, blood, language, and culture have been divided through geopolitics of the superpowers,” Talia Yoon, a resident of Seoul, toldThe New York Times when the paper asked South Koreans for their thoughts on the rapprochement between North and South Korea at the Olympics. “Neither Korea has ever been truly independent since the division.”

In this telling, having Korean athletes march under a unification flag at the Opening Ceremony and compete jointly in women’s hockey isn’t just about the practical goal of ensuring the Games aren’t disrupted by an act of North Korean aggression, or the loftier objective of seizing a rare opportunity for a diplomatic resolution to the escalating crisis over Kim Jong Un’s nuclear-weapons program. It’s also about Koreans—for a couple surreal weeks in February, at least—plucking some control over that crisis from the superpowers that have been so influential in shaping it over the past year.
